What is dysimmune?

Dysimmune neuropathies are etiologically heterogeneous disorders affecting the peripheral nervous system, having diverse clinical presentations [Table 1]. The underlying causes encompass a variety of benign and neoplastic syndromes.

Does CIDP have Fasciculations?

There may be atrophy (shrinkage) of muscles, fasciculations (twitching) and loss of sensation. Patients may have multi-focal motor neuropathy, as they have no sensory loss. Most experts consider the necessary duration of symptoms to be greater than 8 weeks for the diagnosis of CIDP to be made.

How is CIDP diagnosed?

A diagnosis of CIDP is based on an electrophysiologic pattern of multifocal demyelination identified through an EMG/nerve conduction study, elevated CSF (cerebral spinal fluid) protein and, when necessary, nerve biopsy.

Is CIDP a motor neuron disease?

Amyotrophic lateral sclerosis is a degenerative motor neuron disease, whereas CIDP is a demyelinating neuropathy that affects the sensory and motor nerve roots. They both commonly present in patients aged approximately 40 to 60 years, with some variation. Both conditions are more common in men than in women.

What triggers CIDP?

What causes CIDP? CIDP occurs when the body’s immune system attacks the myelin sheaths around nerve cells, but exactly what triggers this is not clear. Unlike Guillain-Barre syndrome, there is usually no infection preceding CIDP.

Can CIDP mimic ALS?

Although some CIDP symptoms may appear similar to those of ALS, ALS does not cause numbness, tingling, or uncomfortable sensations. Also, ALS commonly causes symptoms such as muscle twitching, weight loss, and muscle wasting as well as problems speaking, breathing, and swallowing.

What are the stages of CIDP?

CIDP typically starts insidiously and evolves slowly, in either a slowly progressive or a relapsing manner, with partial or complete recovery between recurrences; periods of worsening and improvement usually last weeks or months.
